OIL-GAS VALVE 'AND.APPARATUS.

SPECIFICATION forming part of Letters Patent No. 644,741, dated March 6,1900.

Application filed August 29, 1899. Serial No, 728,821. (No model.)

To ail whom it may concern.-

Be itknown that I, SAMUEL GUTHRIE, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented an Improvement in Oil- Gas Valves and Apparatus; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to an apparatus for continuously feeding oil to theretorts or gen erators of gas-makin g apparatus and the valve by whichthe feed may be regulated and maintained at a constant flow.

It consists of a cock or valve having a peculiarly-shaped port or portswhereby the amount of flow therethrough may be accurately regulatedwithout reducing the openings in such a manner that they are liable tobe clogged.

It also comprises details of construction of the apparatus, all of whichwill be more fully explained by reference to the accompanying drawings,in which- Figure 1 is a general view of the apparatus. Fig. 2 is asection through the valve-chamber and connection. Fig. 3 is a plan viewof the valve and its chamber.

A represents a supply-tank; B, a pipe leading therefrom and forming acircuit Within which are contained a pump and valves by which thedirection and pressure of the liq uid are controlled and regulated, saidpipe eventually returning into the tank again, so that a continuouscirculation of the oil may be kept up.

0 is the pump, by which the oil is drawn from the supply-tank A andforced through the pipe B.

D is the valve-chamber, through which the oil passes, and E is acontrolling-valve within said chamber, by which the flow to the generator and other portions of the apparatus is controlled.

F is a cock or valve situated in the line of the pipe B, beyond thevalve-chamber D.

G is a branch pipe which leaves the main pipe B between thevalve-chamber D and the cock F and returns into the main pipe at a pointbeyond the cock F, as shown.

11 is an adjustable pressure-valve situated in the line of pipe G.

The operation of the apparatus is as folthrough the circuit of the pipeB and return again to the tank. WVhen it is to feed the oil to theretorts, the cock F may be closed, and the pressure-valve at H isadjusted so that at a certain pressure it will open and allow the oil toflow through it. This valve H has a stem H, surrounded by a spring H andextending into a barrel H and H is a screw-plug entering this barrel andpressing upon the spring H By turning this plug into or out of thebarrel the tension of the spring is varied and the pressure upon thevalve is regulated. In order to show what pressure there may be and toaccurately adjust it to the needs of the apparatus, I have shown anindicating-arm H fixed to the barrel, and upon the flange of thescrew-plug is a marked scale, so that it can be set to provide apressure of forty pounds or other desired pressure. Under this pressurethe pump will then be acting after the valve F has been closed and oilwill flow through the valve H, through the by-pass pipe G, back into thepipe B, thence returning to the tank.- The valve E in the valve-chamberD controls the flow to the generator. This valve is here shown in theform of a flat disk having an inlet-opening E made through it andadapted to connect with the opening of a branch pipe I, which leads fromthe main conducting-pipe B into the bottom of the valve-chamber. Theopening E in the disk is in the form of an elongated segment, whichallows the valve to be turned to a considerable distance without closingthe passage in the pipe I. Upon the opposite side or at other suitablepoints with relation to the port E is made a second port E This port isrectangular in shape with two of its angles standing radially from theperiphery toward the center of the valve and the other two anglesessentially in the line of the arc of travel upon which that portion ofthe valve turns.

E is a passage leading out of the bottom of the va1ve-chamber beneaththe valve E and adapted to be covered or uncovered by the port E whenthe valve is turned. This opening is also made square in shape and insuch position with relation to the port E that when the valve is turnedto fully open the passage the two ports exactly coincide and present arectangular discharge-opening. At this point the elongated port E on theopposite side of the valve will be in line with the supply-passage I, sothat the oil can flow into the valvechamber through this passage and outthrough the port E with the fullest supply that the valve is capable of.

By turning the valve the port E can be moved so as to cut off anydesired portion of the passage E and it will be seen that the passagesubstantially retains its shape to whatever degree it may be diminished,and I thus present as free an opening as possible consistent with thesize, so that the liquid may flow without any danger of its beingclogged. 13y reason of this special form of port I can set the valve Eso that under a given pressure, previously determined by the pressurebrought upon the valve at H, a certain constant flow of oil may bepassed through this valve E to the generator, and when the valve is onceset there will be no variation in the supply until a change is made.

The valve-stem J carries an indicating-arm or pointer K,which projectsover the circular periphery of the top or cap of the valvechamber, andthis is marked with a scale, which indicates the exact position of thevalve and the amount of liquid which will pass through it under thegiven pressure, which is always indicated, as before described, inconnection with the valve H. I have found this form of valve and port tobe exceedingly valuable in connection with this apparatus. It may bemade, as here shown, as a single port, or if the oil is to be conveyedto different parts of the apparatussuch as the retort, the generator,the carbureter, and other partsa plurality of these passages may be madein the disk and so arranged with relation to each other as to producethe regulated supply to the parts of the apparatus desired. The sameform of port is also applicable to a single cook or valve, the size ofthe opening in every case being reduced by the meeting of theoppositely-convergent sides of the stationary passage and the movableport, and the reduction of the opening is always made without anysubstantial change in its shape, thus preventin g the clogging of thepassage, such as would occur when the port is simply narrowedtransversely,while retaining approximately its full length in the otherdirection. The rectangular form of port also insures an accurateregulation of the amount of flow which passes through under a givenpressure and opening of the port.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An apparatus for controlling the flow of the liquids consisting of asupply-tank, a pipe departing from and returning to said tank, a pump bywhich a continuous circulation of liquid within the pipe is produced,means for regulating the pressure Within the pipe, and a valve or cookthrough which the liquid is delivered under pressure, said valvecomprising a rectangular or diamond-shaped port, and ac0rrespondingly-shaped passage over which it is adjustable.

2. The combination of a supply-tank, a pipe connected therewith andmeans whereby a continuous circulation of liquid is produced in saidpipe, and means for regulating the pressure within the pipe including avalve having a diamond-shaped port made through it with two of theangles in the line of movement of the valve, and a seat with aconnecting passage having a port of the same shape with that of thevalve and with two of its angles in the line of movement of thecorresponding angles of the valve.

The combination of a supply-tank, a pipe connected therewith, meanswhereby a continuous circulation of liquid is produced in said pipe, andmeans for regulating the pressure in the pipe including a cook or valvehaving the diamond-shaped port or ports with two of the angles in theline of travel of the valve, the other two approximately at right anglestherewith, and a seat over which the valve moves having acorrespondingly-shaped passage coincident in position with the port ofthe valve whereby the movement of the valve over the port in the seatvaries the size of the discharge-opening without materially altering itsshape.

t. An apparatus for the transmission of liquids consisting of a tank, apipe departing from and returning into said tank, a pump situated withinthe length of the pipe by which the liquid is caused to constantlycirculate under pressure, a by-pass pipe, both ends of which connectwith the main pipe, a cook or valve situated in the main pipe betweenthe ends of the by-pass whereby the flow of liquid may be stopped in themain pipe and transmitted through the by-pass, and a spring-pressedvalve situated in the bypass pipe with means for regulating the pressurethereon.

5. An apparatus for the transmission and distribution of liquids,consisting of a tank, a pump drawing liquid from the tank, a pipethrough which the liquid is transmitted, said pipe returning into thetank, a cock in the length of said pipe whereby the flow therethroughmay be interrupted, a by-pass pipe connecting with the main pipe uponeach side of said cock, a spring-pressed adjustable tension-valvewhereby the flow through the bypass and the pressure under which itpasses are regulated, a valve-chamber connecting with the main pipebetween the pump and said pressure-regulating valve, and one or moreValves by which the flow from said chamber is regulated.

6. In an apparatus for the distribution of liquids under pressure, atank, a pump by which liquid is drawn therefrom, a pipe valve-chamberhaving a diamond-shaped delivery-port, and a corresponding-shapeddischarge-passage which it controls, two of the angles of said portsbeing in the line of movement of the valve and the other twotransversely thereto.

In witness whereof I have hereunto set my hand.
